< FUNCTION DIAGNOSIS >

[5AT: RE5R05A]

DIAGNOSIS SYSTEM (TCM)

If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.

Erase Self-diagnosis

• In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is

stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF. 

• However, this information is erased by turning ignition switch OFF after executing self-diagnostics or by

erasing the memory using the CONSULT-III.

COMPONENT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000005273998

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.

On Board Diagnosis Logic

INFOID:0000000005273999

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1000” with CONSULT-III or 17th judgment flicker without CONSULT-III is detected

when TCM cannot communicate to other control units.

Possible Cause

INFOID:0000000005274000

Harness or connectors
(CAN communication line is open or shorted.)

DTC Confirmation Procedure

INFOID:0000000005274001

NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-III

1.

Turn ignition switch “ON”. (Do not start engine.)

2.

Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

3.

Start engine and wait for at least 6 seconds.

4.

If DTC is detected, go to 

TM-159, "Diagnosis Procedure"

.

 WITH GST

Follow the procedure “WITH CONSULT-III”.

Diagnosis Procedure

INFOID:0000000005274002

1.

CHECK CAN COMMUNICATION CIRCUIT

With CONSULT-III

1.

Turn ignition switch “ON” and start engine.

2.

Select “SELF-DIAG RESULTS” mode for “TRANSMISSION” with CONSULT-III.

Is any malfunction of the “U1000” indicated?

YES

>> Go to LAN section. Refer to 

LAN-14, "Trouble Diagnosis Flow Chart"

.

NO

>> INSPECTION END

P0615 STARTER RELAY

P0615 STARTER RELAY

Description

INFOID:0000000005274003

TCM prohibits cranking other than at “P” or “N” position.

CONSULT-III Reference Value in Data Monitor Mode

INFOID:0000000005274004

On Board Diagnosis Logic

INFOID:0000000005274005

• This is not an OBD-II self-diagnostic item. 
• Diagnostic trouble code “P0615” with CONSULT-III or 14th judgment flicker without CONSULT-III is detected

when starter relay is switched “ON” other than at “P” or “N” position. (Or when switched “OFF” at “P” or “N”
position).

Possible Cause

INFOID:0000000005274006

• Harness or connectors

(The starter relay and TCM circuit is open or shorted.)

• Starter relay

DTC Confirmation Procedure

INFOID:0000000005274007

NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-III

1.

Shift selector lever to “P” or “N” position.

2.

Turn ignition switch ON and wait for at least 2 seconds.

3.

Select “SELF-DIAG RESULTS” mode for “TRANSMISSION” with CONSULT-III.

4.

If DTC is detected, go to 

TM-160, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000005274008
